  • NEEDLELESS SYRINGE USING SUPERSONIC GAS FLOW FOR PARTICLE DELIVERY
    Publication number: 20070299390
    Abstract: A needleless syringe having a membrane (28) which is ruptured by gas pressure to generate a supersonic gas flow in which particles containing a therapeutic agent are injected.
    Type: Application

  • Syringe and capsule therefor
    Patent number: 7182748
    Abstract: A syringe, for use in the delivery of a dose of a therapeutic agent entrained within a pressurized fluid flow, includes an upstream portion, an intermediate portion, a downstream portion, and an actuator mechanism for initiating a flow of the fluid through the syringe. The upstream portion is interfaced with a source of fluid under pressure. The intermediate portion, which is interposed between the upstream and downstream portions, includes first and second members that are coupled together to provide a closed pocket for containing the dose. One of the first and second members is moveable relative to the other within the syringe to provide an open configuration in which the pocket is opened to expose the dose for entrainment by the fluid as it flows through the intermediate portion and to and through the nozzle. Also provided is a capsule formed from the first and second members.

  • Filter
    Publication number: 20040188342
    Abstract: A filter comprising one or more substantially unobstructed ducts (11), each with a longitudinal axis. Each duct has a porous wall which defines a lumen (17) that is surrounded by a helical groove (18) in the respective wall. The ratio of the cross sectional areas, when taken perpendicular to the longitudinal axis, of the totally unobstructed lumen of the duct to that of the open area of the duct, incorporating the helical groove and the lumen, governs the magnitude of the velocities of the fluid flow in the duct. The value of this ratio must allow these velocities to be sufficient to develop a level of interaction between the flow along the groove and the flow through the lumen that produces a flow pattern having a substantially continuous vortex (23), the axis of which is helical.
